Volker Ground Engineering has reported good progress with piling for Luton’s new direct air-rail transit (Dart) scheme.
The £2.7M contract, awarded to Volker Ground Engineering in August last year, is for the steel and concrete works. This includes reinforcing full-length 1,050mm diameter piles to a depth of 20m to the central terminal of the airport.
The firm is currently completing the sheet pile works, which includes silent piling close to the control tower and crossing the airport taxiway during night time possessions to install the sheet piles. This enables the VolkerFitzpatrick Kier joint venture to carry out service diversions.
When complete, the sheet piles will form part of the permanent works for the tunnel.
At the airport’s central terminal, Volker Ground Engineering is installing 17.5m long AZ38-700N sheet piles using a leader rig. According to the firm, piles will be driven using the quiet Dawson Push-Pull system.
Sheet pile and concrete works will start soon on the viaduct piers and bridge.
When completed the £225M Luton Dart will be an automated 2.1km system, seamlessly linking London Luton Airport with Luton Airport Parkway mainline station in well under four minutes. It is due to open in 2021.
The project forms part of Luton’s £1.5bn Investment Framework to transform the town and secure long-term economic growth.
In early 2018, London Luton Airport awarded contracts for the civil engineering works to a VolkerFitzpatrick-Kier (VFK) joint venture to design and construct two stations, a gateway bridge, viaduct and tunnels.
